Control Valve Symbol

Control is shown by normal actuation symbols in Figure 48b, for example, the spring pushes the valve right, decreasing flow, and pilot pressure pushes the valve left, increasing flow This represents a pressurerelief valve which would be connected into a hydraulic system as shown in Figure 48c.

Control valve symbol. The symbol for directional control valve is made of number of square boxes adjacent to each other depending on the number of positions Connections to the valve are shown on these squares by capital lettersusually they are named only in their normal position and not repeated in other positionsactuation system of the valve is also designated. In case none of the valves are actuated, the piston rod stays in last position (The symbol at the bottom displays an FRLunit (filter, regulator, lubricator) The functions of cylinders as well as of airpreparation units will be discussed in a later chapter) 3/2way valves 3/2way valves are mostly used to control single acting actuators. ISA SYMBOLOGY The symbology for the identification of the measurement and control instrumentation on the flow and process diagrams and on the P&ID (Piping & Instrument Diagram), commonly called P&I (Piping & Instrumentation), is generally compliant with the Standard ISA (Instrumentation Society of Automation) identified as S5, that is composed of identification codes and graphic symbols.

Control valves are symbolized by combining the appropriate valve symbol and actuator symbol, as illustrated in Figure 2 Control valves can be configured in many different ways The most commonly found configurations are to manually control the actuator from a remote operating station, to automatically control the actuator from an instrument.
